How should you write an email follow-up? The first thing is that the subject line should be your headline. I always say to people, "Think in headlines," and that the more quickly you can think in headlines, the better results you actually will get. Don't title it: "Follow-Up to My News Release." Please don't do that. They'll hate it. In fact, they'll right over it. The subject line, the actual headline, is benefit-driven. In the body of the email-not as an attachment-is where the press release copy goes.

One thing reporters have told me again and again is, "I hate attachments," and I'm real big on saving them work. The truth is, the more work you can do on your end, so the reporter doesn't have to do any on their end, they're grateful. You are looking to save the reporter-always-time and energy, and to be a resource to them. That's what I would do. That way it keeps it focused, and they know what they're looking at, and they can pull it right up when you are talking to them.
